I  have a test unit AP7131 which was powered down during downgrade process from WiNG5.2.11 to WiNG4.3

Downgrade was applied on secondary firmware.  

Device currently boots on primary firmware and stays in boot mode (LED1 solid red).  

Please advise how to reload operational firmware to this unit in boot mode if it is possible at all.
